Hi folks,

Jim at Linode here. I’m interested in helping resolve this problem, as we’d
like to continue to recommend to Linode customers that they use ClamAV for
their needs.

We generally recommend customers use ClamAV in response to a system
compromise, so they’re just using whatever default configuration that came
with the package they installed. Most customers only run ClamAV when
they’re specifically looking for malware, usually from our recovery
environment (called Rescue Mode). Freshclam is usually run once in Rescue
Mode.

> Linode is our second biggest abuser.

Is this “abuse” being caused by specific IP addresses? Or is the volume of
traffic sending from our network being categorized as “abusive”? Any
specifics you can share would be helpful in us understanding the cause of
this problem. Our impression is that use of ClamAV on our platform hasn’t
meaningfully changed recently.

Would a private mirror help the situation? I believe we could configure
Rescue Mode to fetch updates from whatever private mirror we configure, but
if this problem originates somewhere else, I don’t know how much good that
will do.

- Jim
